` Application ined Angustia, 1920.. A'senat No.. 40337148.; l

To @ZZ whom it may concern: 'v Y. Be it known that I, PoiimnXrER' HILL,citizen of the United. States, residing at Bethesda, in the county ofIndependence and State of Arkansas, have invented new and usefulImprovements in Boats, of which the following is a specification.

This invention relates to boats and comprehends a construction whereinthe hull of the boat is made up of a plurality of hollow cylindricalbodies suitably connected to a motor utilized to rotate said bodies, thecylindrical bodies being equipped with blades or the like to promotepropulsion, the boat being particularly designed for speed.

One of the chief characteristics of the invention resides in the novelconstruction of means for steering the boat, which means embodies amongother features a plurality of rudders connected 'to the collars slidablymounted on a shaft, said collars being controlled through theinstrumentality of a steering wheel which is connected to the collarsthrough the instrumentality of a fieX1- ble element.

The nature and advantages of the invention will be betterunderstood whenthe following detailed description is read in connection with theaccompanying drawings, the invention residing in the construction,combination and arrangement of parts as claimed.

In the drawings forming part of this application like numerals ofreference indicate similar parts in the several views and wherein:

Figure 1 is a side elevation of the boat.

Fig. 2 is a plan view of the hull construction.

Fig. 3 is a sectional view taken on line 3-3 of Fig. 1.

Fig. 4 is a similar view taken on line 4-4 of Fig. 2.

Fig. 5 is an enlarged detail view of one of the collars and ruddersassociated therewith.

Fig. 6 is a perspective view of one of the cylindrical bodies.

Referring to the drawings in detail, A indicates generally the boatconstruction in accordance with my invention, and wherein the hull ofthe boat is made up of spaced parallel side members 10 and a pluralityof hollow cylindrical bodies 11 which are journaled between the sidemembers 10, and each member being equipped with a plurality of riallyassists the cylindrical bodies to effectively engageV` the water topromote propulsion; ...Rising from the side members 10 are a number ofdiagonally disposed bracing elements 13 which support the ioor 14 of theboat and upon which is mounted a motor at 15 of any suitable character.The motor includes a sprocket 17 over which is trained a chain 18, thelatter being also trained over a sprocket 19 as shown. The cylindricalbodies are driven from the motor as is obvious, an endless chain 19being trained over sprockets 2O for this purpose, the sprocket and chainbeing arranged inwardly of the side parallel members 10.

Slidably mounted upon the shaft 21 of the rearmost cylindrical body is aplurality of collars or the like 22, and each being angularlydisposedblades 12 which mate'- provided with an extension as shown.Rud-l v ders 23 for steering the boat are provided and connectedtogether for simultaneous movement by means Vof a rod 24. Each rudderpost has associated therewith a lever 24 which is bifurcated at one endto receive the extension above referred to of the adjacent collar 22.The steering wheel is indicated at 26 and the flexible element 25 istrained about the steering wheel and has its free extremities secured tothe eX- tensions of the collars as clearly illustrated in Fig. 4.Manifestly, byr adjusting the steering wheel one or the other of thecollars are moved upon the shaft 2 1, the eX- tension of these collarsactuates the associated lever 24 to adjust the rudders and consequentlysteer the boat in the proper direction. It is thereby understood thatthe cylindrical bodies 11 may vary in number and size in a boatconstruction, this depending upon the size of the boat and the speedrequired.

While it is believed that from the foregoing description the nature andadvantages `of the invention will be readily apparent, I

nected to each collar, a steering wheel, and

` a connection between the steering wheel and said slidable Collars foreffecting an adjustment of said rudders to steer the boat.

2. In. a boat of the buoyant propelledr type Comprising transverselydisposed paddle wheels, in combination with the shaft of the rear paddlewheel, of collars slidably wheel, and a flexible element connected be-rtween the steering wheel and said "extensions for the purpose specified.

3. In Va boat oftheV buoyant, propelling type comprising transverselydisposed paddle wheels, in Combination with the shaft of the rear paddlewheel, of rudders, means slidab'ly'mounted on the shaft and connectedwith vthe rudders and operating the latter, a steering wheel, and aconnection between the steering wheel and said means for the purposespecified. f l

In testimony whereof I-aix my signature.
